Yes I see the resets on the USB-TTL.
I've gone back to using the pipe() we were discussing in the other thread that lead to memory issues.
I thought the ESP was minimum 3v? http://www.electrodragon.com/w/ESP-12F_ESP8266_Wifi_Board
I'm going to try hooking my components to an entirely seperate power supply, currently my voltage regulator is powered by the 5v output of the espruino (which I assume is just the 5v line from USB), so perhaps it is drawing too much from there and browning out the onboard vreg.
I will note, that quite often I experience an issue where I can't flash to the Espruino once something has gone wrong with the WiFi. I usually have to disconnect power and reflash, I wonder if this is a symptom of the STM32 browning out?
